While some people celebrate the upcoming Halloween holiday by going to spooky haunted houses with friends, two Macomb-based publishers spend their days investigating real reports of haunted places, looking for evidence of paranormal activity.

Kathleen Tedsen of Macomb Township and her sister Beverlee Rydel of Sterling Heights are the authors of Haunted Travels of Michigan. The authors are currently working on their third book in the series.

The sisters recently spoke about their paranormal investigations of the haunted places in Michigan during a live web chat with Pure Michigan Connect.

Some of the haunted spots the authors have investigated include Cobblestone Farms in the Ann Arbor area, The Whitney restaurant in Detroit and The Terrace Inn in Petoskey. The authors also spoke about their experiences and how they became interested in paranormal activity in Q & A stories with the Detroit Free Press and Pure Michigan Connect.

The sisters will be at the White Horse Inn in Metamora Oct. 27 to talk about their haunted travels and at The Terrace Inn in Petoskey on Oct. 28-30 for a Ghost Hunters Weekend. More information about the authors can be found on their website, hauntedtravelsmi.com.
